I have seen boats cross the bars at Nambucca and also Urunga,
Both have good ramps. and dangerous bars.
I holidayed at Valla Beach for many years, but towed my boat to Coffs Harbour to launch, much safer to drive 45 minutes than cross those bars.
I used to watch the Tractor launching boats at Shelly beach, still not an easy launch, Stay safe, Launch at Coffs.
